Asynchronous event-driven IO helps synchronic request handling. All the apps of Node.js are unit asynchronous. This means that in case a Node receives a call for participation for a few Output/Input operations, it’ll execute that operate within the background and continue with the process of different requests. So it'll not await the response from the previous requests.
- Fast in Code execution – Node.js runs on the V8 JavaScript Runtime engine, it is the same engine that is used by Google Chrome. The node contains a wrapper over the JavaScript engine which makes the engine runtime abundant quicker and thence process of requests at intervals Node.js conjointly become quicker.
- Single threads are however extremely ascendible – Node.js uses one thread model for the event process. The responses to these events might or might not reach the server at once. However, this doesn't block different operations which helps to create Node.js extremely scalably. Ancient servers produce restricted threads for handling requests whereas Node.js creates one thread that gives service to sufficient larger numbers of such requests.
- Library Java Script is used by Node.js – It is often another important side of the Node.js from the developer's purpose of reading. This bulk of developer areas unit already is well-versed with JavaScript. Hence, the development of Node.js becomes easier for the developer of the agency who is aware of JavaScript.
- No Buffering – Node.js applications don't buffer any knowledge. They merely output the information in chunks.
